Q: Does it come with a charger?
A: Hi Larry, yes the Helio Strap comes with the charging dock. Please note we do not include the charging cable since it is a standard USB-C cable that is used for all current devices. To be more eco-friendly and reduce waste we have not included it with the watch. If you do not have one already then you can purchase one at your local electronics store, BestBuy, Walmart, Target, Staples, or CVS/Walgreens.
